COMMON PROBLEMS
Function Keys Not Working
Function keys may not work for the following reasons:
o AIX requires "Turnaround Character = CR" in Communi-
cation Setup menu; the default is ETX.
o Perhaps you are using 3151 Model 510/610 and a host
application that requires redefinable function keys.
Common Problems and Questions About 3151 Terminals 1
10/11/95
The Model 510/610 DOES NOT support redefinable function
keys. Recommend using models 310/410.
o An application (example UNIPLEX) may redefine function
keys on models 310/410 and not reset them back to
default values when exiting. The host needs to transmit
3151 "Set All Default Function Keys" command (ESC SP t).
Operator can reset function keys in DEF F setup by
pressing the Clear key.
Insert Key Not Working
If the insert key does not work, change the INSERT CHARACTER
setup option from MODE to SPACE.
Double Characters Displayed
If double characters are displayed, change the OPERATING
MODE from CHAR to ECHO.
Double Prompt When Enter/Return Key is Pressed
The New Line option must be set to CR, not CR/LF. If it is
not, it may cause a double prompt when the Return/Enter key
is pressed. The New Line option can be changed either from
the setup menus or from the host.
Setup:
o Keyboard setup menu. (Models 110, 310, 410 only)
o Select "Default" in Function setup menu.
Host: Set Control 2 Command: ESC ! 9 ( J
3151 Locks Up
If the display locks up:
o Turn on "Status Line" either from keyboard or from
setup. This provides additional information. The fol-
lowing items may be displayed on status line:
HOST BUSY Host told 3151 not to send data to host.
Problem must be corrected at host.
KEYS LOCKED Host sent "Keyboard Lock" command. Host
must send "Keyboard Unlock" command.
Problem must be corrected at host.
HOLD SCREEN Operator pressed "Hold" or "Pause" key;
must press "Hold" or "Pause" key again.
o It may be that the operator accidentally pressed Ctrl-S
| (XOFF); Press Ctrl-Q (XON) to fix the problem.
Common Problems and Questions About 3151 Terminals 2
10/11/95
3151 Does Not Communicate With Host
If the 3151 does not communicate with the host:
o Turn on "Status Line". If "COMM NOT READY 2" is dis-
played, change "Line Control" = IPRTS.
o Host cable may be attached to the auxiliary port rather
than the main port. The main port is on the right-hand
connector ("right hand" as you are looking from the
back).
o The Transmit Data, Receive Data pins may not match the
host communications port. Check pin configuration on
the host system.
o The host system may not have the communications port
enabled.
o If the second session is not working with the
Connectivity Cartridge in Dual Session by Dual Port, the
directions of pins 2 (TD) and 3 (RD) are reversed.
Switch pins 2 and 3 on the communications cable attached
to the Auxiliary port.
Missing or Lost Characters
Missing or lost characters may be caused by a pacing
problem. Reduce line speed to 2400 or 4800 to confirm that
the problem is pacing. Activate pacing at the 3151 and the
host.
Lost Setup Values
If setup values are lost:
o The host could be changing setup values by various 3151
commands: Set Control, Create Viewport.
o Perhaps the user changed the setup options in the setup
menu, but never performed the "Save" operation (move
cursor to "Save" and press space bar).
Cannot Get into Setup
If you cannot get into setup:
o The problem may be a mismatch of keyboards with the
video element.
- If you have a 110 video element with a
310/410/510/610 keyboard, press Ctrl-F4 to enter the
setup.
- if you have a 310/410/510/610 video element with a
110 keyboard, it is impossible to enter the setup.
o It may be that DEC VT200/VT100/VT52 emulation is
selected and the keyboard does not have the DEC Keycap

kit. Press the F3 key, the location of the setup key
when in DEC emulation.
Cannot Print, Not Printing Correctly
If you cannot print or if printing is incorrect:
o Make sure the printer is a serial printer, not a par-
allel printer.
o Make sure the correct cable is being used with printer.
Note the directions of the Receive and Transmit data
pins.
3151 Displays Backward Question Marks
Backward question marks are caused by a frame error; the
parity, word length, stop bits, and line speed must match
the host system.
The (*,/,-,Alt,Ctrl,Page Up,Page Down) Keys Are Not Working
With a model 510/610 in ASCII Mode, the keyboard becomes a
310/410 ASCII layout. This creates the symptom of partic-
ular keys not working. Refer to pages 3-1, 3-2 of the 3151
Guide to Operations, Models 510, 610.
Line Drawing Characters Do Not Display
Line drawing characters not displayed is a result of a char-
acter mismatch between the host and the 3151. 3151 offers
the following character sets: Special Graphics, PC 00437,
PC 00850, ISO 8859/1.2. Determine the character set defined
in 3151 and determine what the host is expecting.
3151 Has Extra Blank Lines
To get rid of extra blank lines, set "Auto LF = OFF" in the
general setup menu, or from the host use "Set Control 3"
command: ESC " 9 = b
Application is Not Displaying Correctly
If an application is not displaying correctly, it could be
that host commands do not match the 3151 settings. 3151 is
set to IBM 3151 and host could be using DEC VT100, WYSE
50/50+. Use 3151 Transparency mode to determine what host
is sending.
Cannot Redefine Function Keys
With model 510/610, redefining function keys is not sup-
ported.
Common Problems and Questions About 3151 Terminals 4
10/11/95
Constant Beep
A constant beep may occur if you are using a cartridge with
model 110. Cartridges are not supported with this model.
Screen is Wavy
If the screen is wavy, change the refresh rate to between 50
and 60 hertz. Press Ctrl-Shift-Hold. 3151 displays key-
board test pattern. Press Ctrl-F10. 3151 displays A or B
(refresh rate). Press F1 to toggle between A or B. Power
off and on 3151.
3151 Displays "HJ"s in CATIA
CATIA supports VT100 emulation, but the IBM 3151 is set to
IBM 3151 mode. The VT100 commands are not compatible with
IBM 3151 mode. Therefore, 3151 requires either IBM/DEC or
Connectivity cartridge which offers VT52, VT100 or VT200.
3151 Backspace Key is Not Working
If the backspace key does not seem to work:
o When using DEC emulation, the Backspace key is a DEL
key, as it is on a DEC terminal.
o It could be that the application is causing the unex-
pected result.
Setup Values of One 3151 Does Not Match Other 3151
The 3151 offers many models and eight cartridges with over
20 emulations, so the setup value could differ among 3151s.
Compare the machine mode of each 3151. Possibilities
include:
o Could have two different models 110 versus 310/410
versus 510/610.
o Perhaps one 3151 has a cartridge and the other does not.
o Both 3151s have cartridges, but they may be different
types of cartridges: IBM/DEC, Expansion, Connectivity,
or WYSE 50/50+.
o Both 3151s have the same cartridge, but the machine mode
is not set the same.
Review your 3151 documentation.
